either in/srv/
or/sharedfolders/
On OMV4 this folder is created and contains links to each share you created

Thanks,
This is totally diffrent error but, I've added this -p 81:81 -p 5000:5000 \ to the docker container and when I go to 192.168.x.x:80 or :5000 I get "unable to connect." in my browser? how come. I want to access the webgui.
